Hi there 👋

I'm Florents, and I'm based in Greece.

I build data tools for a living. Usually with Postgres. My interests lie somewhere between database engineering, AI, web crawling, and data journalism.

I have research, engineering, and leadership experience across the entire data supply chain, from modeling and applying machine learning algorithms to engineering and managing production deployments of big data pipelines.

Some companies I have worked for or consulted for include BCG, Deutsche Telekom, BASF, GfK, XING, BMW, and Advantest, among others. My professional profile is on LinkedIn.

Some of my open-source projects are

• libxicor: libxicor: Pure C implementation of the XI (ξ) Correlation Coefficient

Postgres Extensions

• pgxicor: XI (ξ) Correlation Coefficient available as a xicor(X,Y) aggregate function in Postgres
• pgllm: pgllm: Use LLMs in Postgres
• pgPDF: pgPDF: Query PDFs from Postgres
• jsonb_apply: Postgres JSON with a functional twist
• pgJQ: A Postgres extension that brings jq to Postgres and SQL
• vasco: A Postgres extension that brings correlation discovery to another level.
• cookiecutter-postgres-extension: A cookiecutter template for a Postgres extension

SQLite

• tsellm: tsellm: Use LLMs in SQLite and DuckDB
• liteJQ: jq extension for SQLite.
• WarcDB: A tool that serves crawl data as SQLite databases.

My favorite project is diofanti.org : A tool that monitors public spending in the Greek government.
